Happy anniversary fellas!
And this, now forty five year old clip, still blows my mind:
“That’s one small step for a man, one giant leap for mankind.”
A new look at the “vital signs” of Earth’s climate reveals a stark picture of declining health. As global temperatures rise, so do sea level and the amount of heat trapped in the ocean’s upper layers. Meanwhile, mountain glaciers and Arctic sea ice are melting away beneath an atmosphere where concentrations of three key planet-warming greenhouse gases continue to rise.
Data shows that the climate is changing more rapidly now than it has at any time in the historical record!!! Learn more here.
Strange that Australia’s carbon tax, one of the world’s landmark attempts to stop climate change, is officially no more. More here.
You might think you know your own mind, but your memory can play some confusing tricks on you.
If a chimpanzee appears unusually intelligent, it probably had bright parents. That’s the message from the first study to check if chimp brain power is heritable.
The discovery could help to tease apart the genes that affect chimp intelligence and to see whether those genes in humans also influence intelligence. It might also help to identify additional genetic factors that give humans the intellectual edge over their non-human-primate cousins.
Why are we alive when our bodies are constantly under attack from bacteria, viruses and more? As this video explains, it is thanks to our immune systems that we have an army of cells fighting for our cause.
Have you ever wondered why the sky is dark at night? Well wonder no more …
This video illustrates the powerful implications of six key technologies: 3D printing, robotics, artificial intelligence, the “Internet of Things,” infinite computing and synthetic biology.
Depending on the source of an organism’s body warmth, it may be classified as either an ectotherm or an endotherm. An ectotherm is an animal that warms itself primarily by obtaining heat from the environment, perhaps by sunning itself. Ectothermic animals include most fish, amphibians, and reptiles as well as most invertebrates. An endotherm is an animal that produces most of its own heat and maintains a constant body temperature even when environmental temperatures fluctuate. All birds and mammals are endotherms.
Paleontologists have struggled for years to determine whether dinosaurs were cold-blooded like today’s reptiles or warm-blooded like most modern mammals and birds.
It turns out the answer is neither. Scientists have found evidence for “mesothermy” in dinosaurs. The “mesothermy” found in dinosaurs likely allowed them to move quickly, given that they would not need to constantly eat in order to maintain their body temperature (as do endotherms). As well, the dinosaur’s mesothermic metabolic rate would have decreased the vulnerability of these species to extreme fluctuations in external temperature, allowing them to exert some control of body temperature via internal mechanisms.
US Navy pilot, war veteran, aerospace engineer, astronaut and first man on the moon Neil Armstrong was also an incredible test pilot, with 900 flights in experimental aircraft including the dangerous Lunar Landing Testing Vehicle. On 6 May 1968, he almost died flying one. This is the video of the crash.
The controls on his Lunar Landing Research Vehicle started to go crazy at an altitude of 30m, and the vehicle started to bank dangerously. Armstrong ejected and landed safely, but, according to the post-accident investigation, he would have died had he ejected only half a second later. Learn more here.
